Attached is a project that uses the callback filter to capture frames and then OCR it in a separate thread. Each time you click capture it will save a screenshot in the UI thread and spawn a new thread to OCR the frame you captured.

I used LEADTOOLS v19 visual studios 2013 dotnet 3.5 Win32 for the is project.

This project only allows mpg files to be played, but that can be easily modified.
